Passo 27

Instruções

Você adicionou uma chamada console.log() ao seu script para validar seu array EVAChunks, e agora a chamada não é mais necessária. Para manter o terminal limpo para os próximos passos, exclua o bloco de for loop que registra dados de EVAChunks.

O que fazer:

Testes:

Você deve remover o bloco de `for loop` que registra dados de `EVAChunks`. Exclua o bloco inteiro contendo ambos os loops.
